ELMER C. OSBECK, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO GRAND RAPIDS BRASS COMPANY, OF GRAND RAPIDS, MICHIGAN, A CORPORATION OF MICHIGAN.

. DOOR LATCH.

The present invention relates to latches for refrigerator doors and the like; and its object is, generally, to provide a latch improved in certain respects hereinafter ap- 5 pearing; and more particularly, to provide a latch having improved means for yieldingly holding the latching bolt in certain positions; and further, to provide such a latch adapted to be secured to a door swingably mounted at 1 either of its sides or edges.

This and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure hereinafter particularly described in the 15 body of this specification and illustrated by the accompanying drawings, in which Figure 1 is a front view of a latch and its keeper, a portion of the latchs casing being broken away;

Figure 2 is a left-hand side view thereof;

Figure 3 is a longitudinal sectional view of the latch taken on line 33 of Figure 1;

Figure 4 is a transverse sectional view of the same taken on line 44 of Figures 1 and 25 3; and

Figure 5 is a front view of the same latch carried by a door swingably mounted at its left-hand side or edge. 7

In the embodiment of the invention chosen for illustration by the drawings and for detailed description in the body of this specification, a latch is shown mounted on a door 1, its keeper 2 being mounted on the door frame 3. This latch comprises a latching bolt 4 swingably carried, as shown, on the pivot pin 5 and having an operating handle portion 6 and an oppositely extending portion 7 adapted to latchingly engage in the recess 8 of the keeper to hold the door shut. A detent 9 within the latchs casing 10 is urged to its operative positions by springs 11 on the opposite sides of the bolt, and has a middle recess 12 and recesses 13, 14 spaced on the opposite sides thereof, said recesses being adapted to receive and yieldingly hold, under the pressure of said springs, the bolts lug 15, the middle recess 12 thus holding the bolt in its operative position, i. e., in the position in which its portion 7 latchingly engages in the keepers recess 8; and the recess 13 holding the bolt in its retracted position,

the latch being carried on a door swingably mounted at its right-hand edge or side; and the other recess 14 holding the bolt in re tracted position in case the door is mounted at its left-hand side or edge.

lNhen the open door is slammed shut, the bolts portion 7 strikes and rides up on the slanting face 16 of the keeper and is moved to retracted position, and thereupon strikes the inclined portion 17 of the keeper and is thereby moved downwardly and into latching engagement in the keepers recess 8, as particularly Well seen in Figure 2.

The door is opened by pressing the bolts handle portion 6 downwardly far enough to raise its opposite portion 7 above the high point 18 of the keeper, or to permit the bolt to be urged to such height under the action of the springs 11. It will be seen that the bolt is yieldingly held in its operative position by the recess 12, or in retracted position by the recess 13 or 14 (as the case may be) until the bolt is moved by hand or by the slanting face 16 of the keeper or by its inclined portion 17 far enough to carry it past the high point between the central recess 12 and the recess 13 or 14 toward which it is moving, whereupon the springs urge the bolt to the position toward which it is thus moving.

In the construction shown, the detent 9 has a reciprocating movement guided by the pivot pin 5 along which the detents slot 20 slidably bears.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.

I claim: 1

1. A latch comprising: a bolt movable to latching position and movable in either direction therefrom to retracted position; a detent spring-pressed to operative position and having a recess receiving and yieldingly holding the bolt in latching engagement with the keeper and recesses spaced on opposite sides of the recess first mentioned and respectively receiving and yieldingly holding the bolt in a retracted position.

2. A latch comprising: a bolt movable to latching position and movable in either direction therefrom to retracted position; a detent spring-pressed to operative position and having spaced recesses respectively receiving and yieldingly holding the bolt in a retracted position.

3. A latch comprising: a pivot pin; a bolt mounted thereon swingably to latching posi tion and to a retracted position; a detent having a guided reciprocating movement on said pin, spring-pressed to operative position, and having a recess receiving and yieldingly holding the bolt in one of its said positions.

4. A latch comprising: a swingaloly mounted bolt movable to latching position and to 10 a retracted position; a detent guidedly slidable to operative position and having a recess releasaloly receiving and yieldingly holding the bolt in latching position and a recess releasaloly receiving and yieldingly holding the bolt in retracted position; a spring pressing the detent to operative slid position.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 20th day of November, 1925.
